Serial No. 803,320.

To all whom it may concern Be it known that 1, James H. TALLMAN, of the city of Hamilton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Apparatus for Shocking Grain, of which the following is a specification.

This invention relates to apparatus such as described in my former application, Serial No. G l-2,593, filed August '7, 1911, and provides means for collecting sheaves as they are discharged from a harvester binder, for forming them into a shock and for do positing the shock in a standing position on the ground, nd my object fis to devise apparatus which will. receive the sheaves in a horizontal position, compress the sheaves when a sullicient number have been received to form a shock, lift the shock and turn it into a substantially vertical position, shift it rearwardly at the sameratc as the forvard travel of the harvester binder, lower it to the ground while still holding it and finally release it.

ln the coi'n 'ilete machine I employ the UM-CllflfilSlTl shown and described in rnv co 'iending' application hlo. 765088, filed l lajv 2nd, 1913. hut in order to enahle the mode of operation of the machine to he thor oughlv understood. it will he necessary to repeat the descii 'iption of the said niechm nisin. The purpose of this driving nism is to impart an oscillating rotai rent to a shaft for movin cndwise and thereafter returning}: to its original position.

i is the frame of the apparatus suitably r shaped to support the different parts. this frame is mounted an axle or driving shaft 2., to which connected the ground wheel 5-). half of positive clutch is secured to the axle, while loose on he axle is a crank disk 5. to which issecnred the other half 6 of the clutch. This crank dish 5 has a. grooved huh formed on and con neeted therewith. with which the shifter lever 8 engages in the usual manner. This shifting lever is pivoted at one end and has a coil spring 9 connected therto and to a tionarv part. which coil spring tends move the shifter lever 8 to release the clutch.

It is most convenient to arrange the de- 3W vice so that once the clutch is thrown in it stays in for one revolution of the crank shaft. For this purpose I provide the anti-friction roller 10 secured to the frame andadapted to engage the back of the disk 5, as shown particularly in Fig. 11. A notch l1 1s formed in the disk (see Fig. 12,) in which the roller normally lies, the clutch being released when the parts are in this position. When the shifter lever is moved to throw in the clutch, the roller comes into' a position back of the disk, and as the latter, of course, begins to revolve with the driving shaft, the friction roller rotates on the back of the disk until the not h again comes under the roller, when the spring throws out the clutch, the roller entering the notch. This crank disk is provided with the crank arm .12, which by means of the connecting rod 13, actuates the rock arm 14 secured to the countershaft 15 journaled on the frame. The countershaft has a second rock arm 16 secured thereto which through the medium of the connecting rod 17 actuates the rock arm 18 on the driven shaft 19 parallel with the driving'shaft, (see particularly Figs. 2, 8, 9 a'nd 18.) This driven shaft is mounted in suitable hearings on the frame so as to be capable of both an oscillating rotary and also alongitudinal sliding movement. It is evident from the above description that this driven shaft will be oscillated by the rotation of the driving shaft, the rock arms being so proportioned as to produce this effect. longitudinally in one direction at the end of the oscillatory movement of the shaft in one direction, and to move it in the reverse direction at the end of the oscillatory movement in the other direction. The longitudinal movement of the shaft in one direction is accomplished in the following manner. The projections 20, preferably anti-friction rollers, are formed on a collar secured to the shaft, (see particularly Figs. 2, 8, 9 and 10). These rollers, when the shaft is rotated in the direction of the arrow in Fig. 9 will ride up the inclined planes 21, which are formed on the ends of the members 22 pivoted at 23 on a ring 61 secured to and forming part of the frame of the apparatus. The portions of these members on "which the inclined planes are formed are curved inwardly toward the shaft, so that when the shaft is rotated in the direction of the arrow in Fig. 10, the rollers 20 will pass under the members 22 to re-assume the position in front of the inclined planes without any longitudinal movement being imparted to the shaft. The members 22 are yieldingly pressed toward the shaftby means of the coil springs 21, which are preferably arranged on the bolts 25, each secured to one of the members and passing through the ring 61.

I desire to move this driven shaft From the above description it will. be seen that as the shaft is rotated in the direction indicated by the arrow in Fig. 9 it will be moved longitudinally in the direction towardthe upper side of said figure. To return the shaft to its original position I provide the following mechanism. The shaft 26 is journaled vertically (see particularly Fig. 18) and at its lower end has a rock arm 27 secured thereto, (see particularly Fig. 17 This rock arm, preferably by means of the pivoted link 28, is connected with the shifter lever 29, which is adapted to cooperate with the collar 30 on the movable half 31 of a clutch concentric with the drive shaft. The other half 32 of the clutch is fixed on the driving shaft. Connected with the movable half of the clutch is the sprocket wheel 33. It is evident that by shifting the clutch, the sprocket wheel may be given a. driving connection with the axle as desired. This sprocket wheel is connected by a suitable sprocket chain with the sprocket wheel 34 fastened on the caml shaft 35. This cam shaft has the cam 36 secured thereto. On the vertical shaft 26 is secured a. rock arm 37 preferably provided with an anti-friction roller 38, or otherwise adapted to engage the cam.

Another rock arm 39 is connected to the vertical shaft 26, which by means of the pivoted link 40, is connected with a shifter lever 41 pivoted at one end on the frame of the machine, and adapted in the usual man nor to engage the grooved shifter collar 42 100 secured to the shaft 19. It is evident from the construction described that when the shaft is moved longitudinally as previously described, the vertical shaft 26 will be rocked and the clutch 3l82 thrown in.

Immediatelv the cam shaft 35 is started in rotation. The cam 36 engages the anti-friction roller 88 on the rock arm 37, and after a predetermined period of time rocks the vertical shaft 26 suiliciently far to again no throw out the clutch 3l32, stopping the movement of the cam. The rocking of the. rock arm 37, it will be seen, also acluatcs the shifter lever 1 and moves the shaft 15) toward its original position. of the movement of the shaft in either direction were dependent solely on the mochanism previously described, it is evident that the shaft might become stuck in an interme diate position, and it is desirable therefore 120 to provide means which will snap the shaft quickly to its limit of movement in either direction after a certain portion of the movement has been effected by the means already described. For this purpose I pro- 125 videthe rock arm 43 secured to the vertical shaft 26. The end of this arm is pivotally connected with the slide rod 44-, which is connected to part of the frame of the machine so as to be both slidable and rockable therc- 130 lf the whole in. a reteraloly the rod passes through a journaled pin l5, so as to be freely slidable therein. A coil spring 46 is slipped. on. the rod as and engages the pin 45 and a collar on the rod. This spring is normally in a state or compression. it is evident that the action of the spring would tend to throw the rock arm to e ther side of a line intersec ing the axes of the shaft 26 and the pin to, and that it the pivotal connection between the rod it and the rock arm l?) is moved slightly to either side of the said line of centers that the spring willthrow the roclr arm in either direction and thus through the connections already described move the shaft 19 to its limit of movement in either direction. To insure that the return movement of the shalt 19 to its initial position is not premature, I further provide on the cam till shaft 35 the stop 47 opposite the higher parts oil the cam 36. The rock arm 37 cannot therefore be moved to the position shown in Fig. 8 until this stop has moved clear of the anti-friction roller 38.

F or my purposes, it is necessary to oscillate a second shaft in synchronism with the driven shaft 19. This second shaft 53 is at right angles to the driving shaft 2, and is driven by bevel gearing 54 from the countershaft 15. ltoclr arms 55 are connected thereto for a purpose which will hereinafter appear. The purpose of oscillating and reciprocating the driven shaft 19 is that at certain intervals I desire to give the movable shaft 56 a rocking movement in one direction. I show a. portion of this shaft in Figs. 8 and 9, while it is shown more fully in Figs. 1, 3, at and 5, the shaft being provided with rollers 57 adapted to run on the tracks 48. The end 58 of this shaft is flattened (see particularly Figs. l-i and .15} and a suitable socket 59 is formed in the end of the driven shaft 19- to engage witl' this flattened end. The entended finger 60 is formed on the end oi" the driven shaft 19 to guide the socket on the end of the shaft 19 to the end58 of the shaft 56. This finger is preferably of sutlicient length so that it will engage the end of the shaft 56 a suflicient length of time before the engagement with the shaft 19 to prevent any premature movement of the shaft 39 toward the shaft 56, which would prevent the shaft 19 being in the proper position at the proper time to engage with the end of the shaft 56. The operation of this portion of the apparatus is follows: When the driving shaft is thrown in clutch with. the crank disk 5 both of the driven shafts 19 and lift are oscillated. The initial position of the driven shaft 19 is as shown in Fig. h. The

. first result of the oscillation of the shaft 19.

therefore, is to move it endwise and discugage 1t trom the shaft 56, which is thus left tree to be moved away. it will be noted, however. that as soon as the shalt 19 reaches its limit of longitudinal movement in disengaging from the shaft 56 the clutch- 31. 32 is thrown in and the cam shaft begins at once to rotate. By the time the driven shaft 19., therefore has reached its limit of rotary movement in the original direction the cam 36 has caused its return to its initial position ready to engage the shaft 56. The rollers 28 are now beneath the movable members 2% and as the shaft 19 rocks back to its initial position the rollers pass under the ends of the said members and resume again the position shown in Fig. 8.

Having now described the driving mechanisrn ll will now set out the main features of the rest of the machine, and the manner in which. they derive their motion from the partsalready described. The apparatus is designed to be connected with and drawn by a harvester binder.

At one side oi the frame oi the machine is located the platform 62, (see particularly Figs. l 2 and Over this platform the sheaves from the harvester binder Will be discharged. Their passage may be controlled by means of a hanging gate 63 hinged above and controlling an opening in the frame of the machine. This gate is preferably formed of a series of fingers connected to the rock shaft 64 provided at one end with the crank arm 65, by means of which it may be controlled whenever it is necessary to stop the passage of the sheaves. From this platrorm the sheaves pass to the shock receptacle. This shock receptacle is formed in two parts, each part comprising a curved portion 66 connected to arms 67, which arms are pivoted on the shafts 68 and 53. The former, like the latter, is driven from the transverse shaft 15 by means of bevel gearing the gearing being indicated particularly in Fig. 3 and numbered 70. The curved incmber of each half of the shock receptacle normally lies on one of the shafts 68 and 53 and is connected by means of its arm 6'? with the opposite shaft. The curved morn-hers 66 form between them a semicircular receptacle into which the sheaves are deposited. ld hen the shafts 68 and 53 are rocked the parts of the shock receptacle to the position shown in Fig. 3 the movement being effected through the medium of the links 71 pivoted on the parts of the shock receptacle and pivoted at their other ends to the rock arms 55 fast on the shaft 68 and 53. in Figs. 1 and 2 the parts of the shock receptacle are shown in their normal position. When a. sullicient number of sheaves have been deposited 1 purpose to elevate the shock. grasp it around the mid die by suitable nicclmnism, convey it rearwardly, turn it to an upright position and deposit it on the ground. This is effected by the mechanism l will now describe.

shaft 56 has secured thereto the carriage 72, I

which normally occupies the vertical position shown in'Figs. 1, 2, 6 and 7. On this carriage the cross head 73 is carried, being vertically movable in the guides 74. On this cross head are pivoted the shock gripping arms 75. The arms are suitably curved to embrace the shock. The lower end 76 of the cross head is of some considerable width, and is preferably curved as shown so that when the arms are in the position shown in dotted lines in Fig. 3, the shock is so gripped as to be approximately circular in section. The crosshead is normally held in the position shown in Figs. 6 and 7 by means of the toggle 77, pivoted on the cross headand on the shaft 56. This toggle normally has its centers out ofnline and rests against the stop 7 8. Before the? crosshead can'be lowered this toggle must he rocked outwardly. This position is indicated in Fig. 5. The toggle is tripped at the proper moment by the rotation of the shaft 56, which is efiected as hereinbefore described. I v

On the shaft is secured a curved rock arm 79. The end of this rock arm bears against an anti-friction roller 80 journaled on the end of theconnecting rod 81. The other end of this connecting rod is pivotally connected with one end of the rocking lever 82, which is pivoted on the lower part of the toggle 83, the upper part of which is journaled on the carriage 72 and the lower part on the crosshead 73. Normally this toggle is in the position shown particularly in Figs. 6 and 7.

The outer end of the connecting rod 81 is guided in the slotted guide 84 connected with the lower part of the toggle 83 and normally substantially parallel to the upper part of the toggle. As soon as the shaft 56 starts to rotate the curved rock arm 79 presses against the roller 80 and breaks the toggle 77, which allows the cross head 73 to drop to the position shown in Fig. 3. In this position the toggle 83 will have straightened out and its center pivot 85 will have crossed the line of centers of its end pivots, occupving the position shown in Figs. 5 and 20. The toggle will then hold the cross head in the position to which it has moved until the center pivot is pushed to the other side of the line of centers as hereinafter described.

When the crosshead has dropped, the toggle 83 will contactwith the cross bar 86 of the crosshead, which prevents it rocking too far past the line of centers and collapsing again on the other side. The inner ends of the shock gripping arms extend pasttheir pivots 87 and are connected with the lower ends of the links 88, the upper ends of which are pivotally connected with the lower end of a rod 89 sliding in suitable parts of the carriage 72. The upper end of this rod is provided with an adjusting nut 90 screwed thereon and provided also with a clamp nut. When the cross head drops, the nut 90 contacts with the member 91 of the carriage and holds up the inner ends of the shock gripping arms 75. The weight of the descending parts thus causes the arms 75 to swing inwardly to grip the shock. These shock gripping arms work through the slots or divisions 92 dividing the parts of the shock receptacle transversely.

Each slot, it will be noticed has an enlargement 93 at its inner end. The end of each shock gripping arm is provided with the anti-frictionrollers 94, which form an end to each arm of greater width than the arm. These rollers will not pass through the main portion of the slots, but will pass freely through the enlargements. The result is that the shock gripping arms pass downwardly outside the parts of the shock receptacle until the arms have descended and the parts of the shock receptacle have ascended sufficiently far to enable the rollers 94 to pass through the enlargements 93. This occurs when the lower ends of the shock gripping arms have passed well down toward the bottom of the shock receptacle, when they spring inwardly and grip the shock, relieving the shock receptacle from the duty of supporting the same. To assist in compressing the shock and to raise its lower side above the enlargements 93, I provide the compressor bars 95, each pivoted on one half of the shock receptacle and having its other end adapted to ride up the curved innersurface of the opposite half, (see Fig. 3.) lVith these compressor bars the curved member 76 of the cross head cooperates to compress the shock vertically, the lateral compression being, of course eifected by the inward swing of the parts of the shock receptacle.

When the parts of the shock receptacle rise, as shown in Fig. 3, a gap is left between the shock receptacle and the platform 62, into which a sheaf might drop. I therefore provide the bars 96 which are pivoted on the part of the shock receptacle adjacent the platform near its upper end and which ride over a bar 97 below the platform, being thus drawn out as indicated in Fig. 3 to close the gap when the parts of the shock receptacle swing up.

The carriage being supported on the shaft 56 and being pivoted thereon, requiresa suitable support to hold it in its vertical position. The carriage is supported and also swung as hereinafter described by means of the crank arms 98, which are connected by means of the wrist pin 99. One of these crank arms is secured to the end of the shock gripping arms are opened wide, leaving it entirely free and standing on the ground.

lit will be noted that a coil spring 122 is placed on a rod 123, which is pivotally connected at one end with the center of the toggle 77, its other end passing freely through ahole in a supporting bar 124 extending outwardly from the carriage. This spring, as soon as the curved rock arm 79 has started the movement of the cross head to its normal position by rocking the toggle 83, assists in the return movement owing to its tendency to straighten out toggle 77 and return it to the position shown in Figs. 1, 2, 6 and 7.

As soon as the shock has been released the springs 115 return the track extensions 111 tov their normal position. movement of the crank arms 98 returns the shaft 56 towardits initial position where it is again engaged by the shaft 19 aspreviously described. Before this vertical position is reached, the projections 109 have engaged the flanges 110 and released the latches 107 as has been described."

The final movement to the vertical position is by means of the following spring actuated mechanism. Curved tracks 125 are pivoted by their ends at opposite sides of the machine. These tracks are yieldingly drawn upward by means of the, coil springs 126, each connected to oneof'the tracks and toe bracket 127 connected to the frame of the apparatus. On each crank arm 98 adjacent' to the axis on which it rotates, is secured an arm 128 provided with an anti-friction roller. These engage the curved tracks 125 before'the shaft 56 hasreturned to its initial position and put a tension on the springs. As soon as the shaft 56 reaches its initial position and is engaged by the shaft 19 the driving mechanism goes out of clutch and the tension of the springs 126 is depended upon to make-the final movement in return of the carriage to its initial vertical position with the wrist pin of the cranks 98 at the bottom of the guides 100 and lying in engagement with the notches 101. v

It should be noted that the instant the shock gripping arms 75 have grasped the shock that the parts of the shock receptacle begin to return to their normal position, and no rotary movement of the shaft 56 takes place until the parts of the shock receptacle have returned to their normal position. This delay in the rotation of the shaft 56 is due to the shape of the notch 59 in the end of the shaft 19. This is made so wide relative to the flattened end 58 of the shaft 56 that the shaft 19 may effect a considerable movement of rotation before a driving en gagement occurs with the sides of this flattened end, thus giving the dwell desired.

The continued 7 binder, the gate 63 4s raised toliold back on the binder deck on the harvester any' sheaves which may be bound while the shocker is operating. The shifter lever-,8 is then operated, throwing"the machine v in gear. \This effects a rotary movement of the shaft 19, followed by an endwise movement. This movement of the shaft 19 effects the partial-rotation of the shaft 56 which trips the cross head carrying the shock supporting arms, thus pausing the latter to descend to grasp the shock which has been lifted and compressed by the upward and inward movementof the shock receptacle, which takes place as soon as the machine is put in gear. Following these preliminary movements, the shaft 19 is moved endwise to release the shaft 56. At the time that the shaft 19 is moved endwise to release the shaft 56, the shaft 35 is started in motion due to the throwing in of the clutch 31-32. The shaft 56 is then pushed backward through the rotation of the crank arms 98 rocking the sheaf carrying means to horizontal position and carrying the shock which has been raised from the shock receptacle rearwardly at the same rate as the forward travel of the apparatus. The shock is then lowered to the ground, the shock gripping 'arms released and the parts returned to their normalposition as already described. The driving mechanism is then thrown out of gear as already described. The apparatus is also preferably provided with a butt board 129 (see particularly Figs. 1 and 2), which butt board is fixed to the frame of the apparatus. A head board 180 is also provided connected by means of the arms 131 to the carriage 72, (see particularly Figs. 1, 2, 4: and 5.) Between this head and butt board the sheaves are dropped, and being thus restrained the sheaves form a symmetrical shock with the bottoms of the sheaves substantially even: giving the shock a good 'base to stand on. It will be noted that us the head board travels with the carriage 72, that it exerts a restraining influence on the shock until the latter is tipped to the vertical position ready for dumping.
